Free pile design calculators
Real engineering tools, not formula-pluggers: each calculator runs PileCalc's validated analysis engine — the same p-y, NAVFAC and Vesić implementations checked against LPILE and RSPile — directly in your browser, free.
Lateral pile deflection
Deflection, moment and shear of a laterally loaded pile by the actual p-y finite-difference method — not a formula approximation.
Open calculatorP-y curve generator
Build the p-y curve for any of six published models at a given depth — plotted, tabulated, and exportable by hand.
Open calculatorPile capacity
Ultimate and allowable axial capacity — side friction, end bearing, and uplift — by the NAVFAC DM-7.02 method.
Open calculatorPile settlement
Settlement at your working load from the t-z load-transfer curve, with Vesić's three-component breakdown.
Open calculatorSPT correlations
Standardize measured N to N₆₀ and (N₁)₆₀, then view the applicable public Caltrans sand-property ranges and their clearly labeled midpoint.
Open calculatorPile group efficiency
Preliminary geometric η from WSDOT WA-RD 827.1 Equation 2.29, not an equivalent-block or design-resistance result.
Open calculatorNeed the full analysis, not a quick check?
Layered soil profiles, all seven p-y models, cyclic loading, pile groups, drilled shafts, PDF reports and saved projects — free to start.
